What I want is to go through this list in a selection of three. 
 
1. After the first occurrence pattern "Processing" i have 2 lines.Save these 2 lines in a separate file.save the file size of this file in variable "a" 
 
2. After 2nd occurrence of "Processing", I have 2 lines.Save these 2 lines in a separate file.save the file size of this file in variable "b" 
 
3. After 3rd occurrence of "Processing", I have 2 lines.Save these 2 lines in a separate file.save the file size of this file in variable "c" 
Now I'd perform an operation $a+$b/$c >> RESULT.txt. 
 
Then select other triplet i.e. 4th,5th and 6th occurence of "Processing" save the calculation to RESULT.txt and so on. 
 
[EDIT:]  I did tried these two codes, but they dont cater to the triplet selection 
Code
 perl -ne 'BEGIN{ $/="Processing"; } if(/^\s*(\S+)/){ open(F,">$1.out")||warn"$1 write failed:$!\n";chomp;print F "gi", $_ }'
 
Code
awk -vRS="Processing" '{ print $0 > "file"t++".out" }' matrix.txt
